Compliance 3-Cat is the proportion of times the two MPs in a pair vote the same way in a given session, with absence considered equivalent to abstention. Similarity 3-Cat is the average vote similarity between the two MPs in a pair, with absence considered equivalent to abstention. Similarity Recode is the pair-level average vote similarity, with absence coded as closer to a no vote than abstention. Neighbor is a dummy variable equal to one if the MPs in the pair are randomly assigned to sit next to each other during that session. Same Party is equal to one if both MPs in the pair are in the same party for that session. Dyadic-robust p-values are in square brackets. Randomization inference p-values (1000 draws) are in curly brackets. Special sessions and a short session (2017) are excluded. For lead and lag specifications, sessions are also dropped where lead/lag would be a special/short session or a session in a different parliamentary term. Strata FE are dummy variables for whether both MPs in a pair were pre-assigned seats, one MP in a pair was pre-assigned a seat, or neither MP in a pair was pre-assigned a seat. *** p<0.01, ** p<0.05, * p<0.1.} \\ \end{tabular} }
